Questions and Answers

What is the formula for calculating the probability of an event?

  • P(E) = Number of favorable outcomes * Total number of outcomes
  • P(E) = Total number of outcomes - Number of favorable outcomes
  • P(E) = Number of favorable outcomes / Total number of outcomes (correct)
  • P(E) = Total number of outcomes / Number of favorable outcomes

    • If two events A and B are independent, what is the probability of both A and B occurring?

  • P(A and B) = P(A) / P(B)
  • P(A and B) = P(A) * P(B) (correct)
  • P(A and B) = P(A) - P(B)
  • P(A and B) = P(A) + P(B)

    • In a standard deck of 52 playing cards, what is the probability of drawing a heart or a king?

  • P(heart or king) = 1/13
  • P(heart or king) = 1/4
  • P(heart or king) = 9/26 (correct)
  • P(heart or king) = 17/52
